The upper frame 5 is fixed to the bottom of the sieve 6.

또한, 상부프레임(5)에 설치된 회동축(7)의 양측에 구동바퀴(8)를 장치하고 일단부가 회동축(7)에 고정된 제1지지대(9)의 타단부를 보조축(10)에 유동되게 연결하며, 하단부가 상기 하부프레임(1)에 유동되게 연결된 제2지지대(11)의 상단부를 보조축(9)에 유동되게 연결한다.In addition, the driving wheels 8 are provided on both sides of the rotational shaft 7 provided in the upper frame 5, and the other end of the first support 9, one end of which is fixed to the rotational shaft 7, is provided with the auxiliary shaft 10. It is connected to the fluid flow, and the lower end is connected to the upper end of the second support (11) fluidly connected to the lower frame (1) to the auxiliary shaft (9).

또한, 보조축(7)에 제1, 2스프라켓(12a)(12b)를 고정설치하고 구동바퀴(8)의 회동축(7)과 상기 보조바퀴(3)의 회동축(13)에 각각 스프라켓(14)(15)을 고정설치하여 제1,2스프라켓(12a)(12b)과 각각의 스프라켓(14)(15)이 각각의 체인(16)(17)에 의하여 연결되도록 장치한다.Further, the first and second sprockets 12a and 12b are fixed to the auxiliary shaft 7 and the sprockets are respectively provided on the rotation shaft 7 of the drive wheel 8 and the rotation shaft 13 of the auxiliary wheel 3. (14) (15) is fixedly installed so that the first and second sprockets (12a) and (12b) and the respective sprockets (14) and (15) are connected by the respective chains (16) and (17).

이 설명보호 18은 실린더(4)를 작동시키기 위한 승하강레버이며, 19은 구동바퀴(8)의 회동을 조절하는 제어간이다.This explanation protection 18 is a lifting lever for operating the cylinder 4, and 19 is a control period for adjusting the rotation of the driving wheel 8.

이와같이 구성된 본 발명은 도 1에 도시된 바와같이, 구동바퀴(8)가 상승된 상태에서 보조바퀴(3)가 지면에 지지되도록 보조바퀴(3)를 이용하여 이동하는 것이다.As illustrated in FIG. 1, the present invention configured as described above moves by using the auxiliary wheel 3 so that the auxiliary wheel 3 is supported on the ground in the state in which the driving wheel 8 is raised.

즉, 구동바퀴(8)가 상승되고 보조바퀴(3)가 하강됨에 따라 의자체(6)의 높이가 상승되므로 장애인의 높은 위치에서 각종작업을 수행하는 것이며, 또한, 이동하고자 할 경우에는 구동바퀴(8)를 손으로 돌리면, 회동축(7)의 동력이 체인(16)을 통하여 보조축(7)에 전달된 후 체인(17)을 통하여 회동축(13)에 전달되므로 보조바퀴(3)가 회동되어 이동이 가능한 것이다.That is, as the driving wheel 8 is raised and the auxiliary wheel 3 is lowered, the height of the chair body 6 is increased, so that various operations are performed at a high position of the handicapped person. Turning 8 by hand, the power of the pivot shaft 7 is transmitted to the auxiliary shaft 7 through the chain 16 and then to the pivot shaft 13 through the chain 17 so that the auxiliary wheel 3 Is rotated and can be moved.

이때, 구동바퀴(8)가 대형으로 형성되고 보조바퀴(3)는 소형을 형성되어 있기 때문에 구동바퀴(8)를 돌리는 힘이 적어도 보조바퀴(3)의 회동이 가능하므로 지면이 평탕하지 못한 곳에서 적음 힘으로 이동이 가능한 것이다.At this time, since the driving wheel 8 is formed in a large size and the auxiliary wheel 3 is formed in a small size, since the force for turning the driving wheel 8 can rotate at least the auxiliary wheel 3, the ground is not smooth. It is possible to move with less force.

작업이 완료되어 일반적인 휠체어의 기능으로 사용하고자 할 경우에, 승하강레버(18)를 조작하면, 실린더(4)의 피스톤로드(4a)가 하강되면서 상부프레임(5)에 고정된 의자체(6)와 구동바퀴(8)가 하강되므로 도 2에 도시된 바와같이, 보조바퀴(3)는 상승되고 구동바퀴(8)가 지면에 지지된다. 이러한 상태에서 구동바퀴(8)를 손으로 돌리면 보조바퀴(3)는 공회전되고 구동바퀴(8)에 의하여 이동이 가능한 것이다.When the work is completed and wants to use as a function of a general wheelchair, when operating the lifting lever 18, the chair body (6) fixed to the upper frame (5) while lowering the piston rod (4a) of the cylinder (4) And the driving wheel 8 are lowered, as shown in FIG. 2, the auxiliary wheel 3 is raised and the driving wheel 8 is supported on the ground. In this state, when the driving wheel 8 is turned by hand, the auxiliary wheel 3 is idle and movable by the driving wheel 8.

그리고 재차 구동바퀴(8)와 의자체(6)를 상승시키고자 할 경우에 승하강레버(18)를 조작하면 실린더(4)의 피스톤로드(4a)가 상승되면서 구동바퀴(8)와 의자체(6)가 상승되는 것이며, 구동바퀴(8)와 의자체(6)의 상승정도는 승하강레버(18)의 조작에 의하여 조절할 수 있는 것이다.When the driving wheel 8 and the chair body 6 are to be raised again, when the lifting lever 18 is operated, the piston rod 4a of the cylinder 4 is raised to drive the wheel 8 and the chair body. (6) is to be raised, the degree of lift of the drive wheel 8 and the chair body 6 can be adjusted by the operation of the elevating lever (18).

상기 제어간(19)은 구동바퀴(8)를 회동되게 하거나 정지시키기 위한 것으로 이동시에는 구동바퀴의 회동을 간섭하지 않으며, 정지하고자 할 경우에 제어간(19)에 의하여 브레이크기능이 수행되어 구동바퀴(8)와 보조바퀴(3)가 불의하게 회동되는것이 방지되는 것이다.The control section 19 is to rotate or stop the driving wheel 8, and does not interfere with the rotation of the driving wheel when moving, and the brake function is performed by the control section 19 to stop the driving wheel. (8) and the auxiliary wheel (3) are prevented from being inadvertently rotated.

상기한 바와같이, 본 발명은 장애인이 휠체어를 사용함에 있어, 휠체어의 고유기능으로 사용할 수 있는 뿐 아니라 높낮이가 조절되므로 휠체어에 앉은 상태에서 각종작업을 수행할 수 있는 효과가 있는 것이다.As described above, in the present invention, the disabled person can use the wheelchair, as well as the unique function of the wheelchair, the height can be adjusted, so that the various tasks can be performed while sitting in the wheelchair.

또한, 보조바퀴로 이동할때에 지면이 평탄하지 못한 곳에서 적은 힘으로 이동이 가능할 뿐 아니라, 타인의 도움없이 장애인 자신이 휠체어를 이동시킬 수 있는 것이다.In addition, when moving to the auxiliary wheel can not only move with a small force in a place where the ground is not flat, the disabled person himself can move the wheelchair without the help of others.

본 발명은 장애인이 휠체어에 앉은 상태에서 각종 작업을 할 수 있으므로 척추 또는 하반신 장애인의 재활에 크게 기여할 수 있는 유익한 발명인 것이다.The present invention is a beneficial invention that can greatly contribute to the rehabilitation of the spinal cord or lower body disabled people can perform a variety of tasks in a disabled person sitting on a wheelchair.
